Materials Data on Al2Bi7Ru(BrCl4)2 by Materials Project

Abstract

RuBi7Br2(AlCl4)2 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of eight AlCl4 clusters and two RuBi7Br2 clusters. In each AlCl4 cluster, Al is bonded in a tetrahedral geometry to four Cl atoms. There are a spread of Al–Cl bond distances ranging from 2.15–2.18 Å. There are four inequivalent Cl sites. In the first Cl site, Cl is bonded in a single-bond geometry to one Al atom. In the second Cl site, Cl is bonded in a single-bond geometry to one Al atom. In the third Cl site, Cl is bonded in a single-bond geometry to one Al atom. In the fourth Cl site, Cl is bonded in a single-bond geometry to one Al atom. In each RuBi7Br2 cluster, Ru is bonded in a 9-coordinate geometry to one Ru and eight Bi atoms. The Ru–Ru bond length is 2.91 Å. There are a spread of Ru–Bi bond distances ranging from 2.82–2.97 Å. There are seven inequivalent Bi sites. In the first Bi site, Bi is bonded in a 5-coordinate geometry to four Bi atoms. There are a spread of Bi–Bi bond distances ranging from 3.15–3.22 Å. In the second Bi site, Bi is bonded in a 4-coordinate geometry to two equivalent Ru and two Br atoms. There are one shorter (2.95 Å) and one longer (2.99 Å) Bi–Br bond lengths. In the third Bi site, Bi is bonded in a 4-coordinate geometry to two equivalent Ru and two Br atoms. There are one shorter (2.96 Å) and one longer (3.02 Å) Bi–Br bond lengths. In the fourth Bi site, Bi is bonded in a distorted single-bond geometry to one Ru and three Bi atoms. There are one shorter (3.10 Å) and one longer (3.11 Å) Bi–Bi bond lengths. In the fifth Bi site, Bi is bonded in a 1-coordinate geometry to one Ru, three Bi, and one Br atom. The Bi–Bi bond length is 3.07 Å. The Bi–Br bond length is 3.40 Å. In the sixth Bi site, Bi is bonded in a 1-coordinate geometry to one Ru and three Bi atoms. The Bi–Bi bond length is 3.09 Å. In the seventh Bi site, Bi is bonded in a distorted single-bond geometry to one Ru and three Bi atoms. There are two inequivalent Br sites. In the first Br site, Br is bonded in a 2-coordinate geometry to two Bi atoms. In the second Br site, Br is bonded in a 2-coordinate geometry to three Bi atoms.
